Hi All,
I've run into a problem during call transfer. 
I have a CISCO switch calling Freeswitch that set bypass_media to true and
makes a bridge to IVR platform (its actually a VXML browser).
When IVR platform then tries to transfer a call using REFER the Freeswitch
sends INVITE to the gateway in order to perform call transfer but Media part
inside SDP is empty - as a result gateway returns  488 Not Acceptable Media
and transfer fails. 
Is it possoble to make Freeswitch to send meaningful SDP inside INVITE? I
would expect it to copy SDP from original incoming call - but this does not
